My question involves criminal law for the state of: TN
A Judicial Subpoena for Documents, an Application for Judicial Subpoena, & general cover letter were faxed by a police detective to a major phone/internet company requesting a user's records. This company responded by faxing the user's records to the police detective. Both subpoenas faxed were not signed or dated by police detective, officer of the court, or judge. Is that a common practice in TN to submit unsigned & undated subpoenas requesting user records to a company that has in their policy, before responding to any legal demand, determination is made as to receiving the correct type of demand, as well as if the agency failed to send correct type of demand, they reject the demand?
